Some Basic Principles of the Biochemistry of the Elements
Essentially two different categories of basic principles are dealt with here. One is a set of principles dealing with the biological selection of elements (Section 2.1), whereas those in the other category are related to physicochemical properties of elements and their compounds (Section 2.2.). Biological systems could be expected to adapt themselves to the use of particular elements for their needs as a result of many factors, important among which should be “usefulness” and “availability”. The extent to which an element and its compounds are found to be appropriate will depend heavily on physicochemical properties relevant to enzymatic or other biological functions, such as reduction potential and acid-base character. Some of the basic parameters that determine these properties will be discussed in Section 2.2.
